Here is some brief info about NppExec for new users:
* NppExec adds a Console window at the bottom of Notepad++'s window;
This Console window allows to run different console programs directly in it;
Also there is Plugins -> NppExec -> Execute… window that allows to execute NppExec’s scripts (set of commands).
* NppExec’s commands and variables are listed in the “NppExec.txt” file.
* To get more details, type “help” (without the quotes) directly in NppExec’s Console. To get a detailed help about any NppExec’s command, type “help <command>” - e.g. “help npp_open” or “help set”.
And don’t forget about Plugins -> NppExec -> Help/Manual.

What’s new in NppExec v0.6 beta 1:
* changed: now the Execute dialog’s auto-completion pop-up uses the same upper/lower case as the first character of a word being typed (e.g. Npp -> NPP…; npp -> npp…);
also: now the auto-completion pop-up’s height is limited by the number of its items
+ new commands: SCI_FIND, SCI_REPLACE
+ new commands: TEXT_SAVETO, TEXT_LOADFROM
+ Function Parser has been updated to support the bitwise operators: ~, |, &, << and >> (thanks to Juha Nieminen and Joel Yliluoma for their advice)
+ $(LAST_CMD_RESULT) - result of the last NppExec’s command (1 - succeeded, 0 - failed, -1 - invalid arg)
- fixed: parameters of sci_sendmsg/npp_sendmsg were truncated to 32-bit in 64-bit NppExec
- fixed: now pasting to the Console via Shift+Insert is equal to Ctrl+V

Yes, I think the version of the 32-bit one can be updated as well.
I remember I was registered at the original 32-bit Plugin Manager site, where the plugin descriptions are present. Is it still relevant? If so, I just need to find my old credentials there, to be able to update the information.

But it seems like the 32-Bit Plugin Admin System at https://npppm.bruderste.in has a malfunction again. For example the PluginManager itself was released as v1.4.11 at March 13th but in the plugin list it still displays the release infos of its v1.4.9. The current version is only available via development plugin list.

Hopefully the schedule is still working. There is a 2 week time schedule to take over the changes from the dev list to the official list to allow for beta testing before going live. PM was build on 2018-03-13, but added to the 32bit list on 2018-03-29 after some testing with the 64bit. So maybe still on the schedule as merge is done on Monday to my knowledge.

@chcg
I rolled back to PluginManager v1.4.9 and it didn’t offer v1.4.10. Or was this version not published via Plugin Admin System?

@Vitaliy-Dovgan
The version info of NppExec’s DLL file states that it is v0.6.0. The version info in the Plugin Admin System is set to v0.6.0.1. Therefore the offer to update the plugin doesn’t disappear.
